Hi everyone i m trying to put a threshold on a grayscale image and i m doing it this way.
Looping through mat image.

I m doing my own color conversion where i need access to individual red green and blue values.
Right now your loop will probably run areasize number of times 15 times from what you write.
When you get a list of image files their names will be stored inside of a structure.
Working with cell arrays.
But every time the loop runs you will overwrite your crop variable because it is not indexed.

That a for loop reads the image pixel by pixel and if the value of the pixel is less than 0 5 sets its value to 0 and if it is more than 3 sets it to 256.
If you happen to know that all of your images are exactly the same size you can use a regular numeric.
Simply index the crop variable and then you should end up with a 15 by 1 vector guesswork since i dont know your dimensions or the imcrop function.

Then i need to loop through the next two columns in the excel sheet columns 3 4 and assign these to x and y and run the calculation again and then plot the results.

I already have the code for the calculation so i m just stuck on looping through the columns and the graphing.

This is 0 or 1 depending on whether it is 0 image new image in2 0 image new i j image in2 i j 0 so scale the values up with a simple multiplcation image new image new.
Loop through mat images and compare each.
I ve tired looping through using the image data property and getting the colors similar to code below int rows image rows.
I would like to loop through image data extremely fast.
We ll use a cell array to store the data coming from the different images since it allows for each image to be a different size.
Byte datargb image data.
